Evacuation first
Acrylic heats quickly when chips remain in the cut. A polished single-flute geometry is commonly used to encourage a continuous chip and effective evacuation.
Warning signs
Sticky chips, whitening or material welding back together indicate that you should stop and review feed, spindle speed, extraction or tool condition.
Validation
Always test on scrap with stable workholding and suitable protection. Manufacturer values remain the priority.
Important
The stated parameters are starting points. Test progressively on scrap and always respect manufacturer limits.
